Answer :

 Diffusion is the process of water molecules from a high concentration region to low concentration.When particles diffuse ,they will break down to simpler particles.
Causes:
Due to the motion of paticles the particles will collide each other and mix.

The particles move from higher concentration to lower concentration during diffusion.

What happens to particles in diffusion?

Diffusion occurs when gas molecules disperse throughout a container. In diffusion, the movement of particles occurs from higher concentration region to lower concentration region.

So we can conclude that the particles move from higher concentration to lower concentration during diffusion.
